Quality Assurance for Hot Rolled Steel Bars
Basic Tests:
- Tensile Test: Measures yield strength, tensile strength, and elongation.
- Hardness Test: Assesses wear resistance using Brinell or Rockwell methods.
- Chemical Analysis: Ensures compliance with element content standards.
- Surface Quality Check: Inspects for cracks and surface defects.
Extreme Tests:
- Bend Test: Evaluates ductility and plastic deformation.
- Fatigue Test: Assesses cyclic loading performance.
- Cold Bend Test: Checks for cracks under cold bending.
- Metallographic Analysis: Observes microstructure.
If you have specific requirements, we can customize additional tests to meet your needs.
To ensure the safe and secure transportation of our steel bars, we use robust packaging methods:
-
Secured Bundling: Bars are securely bundled with steel straps and wooden supports. Finished products are shipped in wooden crates.
-
Protective Coatings: Our steel bars are coated to prevent corrosion and damage during transit. Additional coating options are available upon request.
-
Labeling and Documentation: Each shipment is clearly labeled and comes with detailed documentation for easy tracking.
Several factors influence the performance of hot rolled steel bars, affecting their suitability for various applications.
- Humidity and Corrosion: Accelerated by humidity, acids, and salts.
- Temperature Variations: High temps reduce strength; low temps increase brittleness.
- Mechanical Stress: Cyclic loads and impacts cause fatigue and cracks.
- Chemical Environment: Acids and pollutants speed up corrosion.
- Physical Damage: Scratches affect performance; coatings improve resistance.
- Storage Conditions: Poor storage accelerates corrosion; proper storage maintains quality.
Hot rolling can lead to poor surface quality and dimensional accuracy, but our advanced process ensures you need not worry about these issues.
Proper storage is vital to maintain the quality and performance of hot rolled steel bars.
- Dry Environment: Store in dry areas, preferably indoors or under cover, to avoid moisture.
- Good Ventilation: Ensure well-ventilated storage to prevent moisture buildup.
- Off-Ground Storage: Use wooden pallets or supports to keep bars off the ground.
- Categorized Storage: Store by grade, size, and shape for easy access and inventory management.
- Avoid Ground Contact: If outdoor storage is necessary, use waterproof tarps or plastic sheets.
- Temperature Control: Control temperature to avoid extreme changes.
